NAME

Bio::Symbol::Symbol - A biological symbol

CONTENTS

SYNOPSIS



    use Bio::Symbol::Symbol;
    my $thymine = Bio::Symbol::Symbol->new(-name => Thy,
                                          -token=> T);
    my $a = Bio::Symbol::Symbol->new(-token => A );
    my $u = Bio::Symbol::Symbol->new(-token => U );
    my $g = Bio::Symbol::Symbol->new(-token => G );

    my $M = Bio::Symbol::Symbol->new(-name  => Met,
                                    -token => M,
                                    -symbols => [ $a, $u, $g ]);

    my ($name,$token) = ($a->name, $a->token);
    my @symbols       = $a->symbols;
    my $matches       = $a->matches;



DESCRIPTION

Symbol represents a single token in the sequence. Symbol can have multiple synonyms or matches within the same Alphabet, which makes possible to represent ambiguity codes and gaps.

Symbols can be also composed from ordered list other symbols. For example, codons can be represented by single Symbol using a compound Alphabet made from three DNA Alphabets.

This module was implemented for the purposes of meeting the BSANE/BioCORBA spec 0.3 only.

Please direct usage questions or support issues to the mailing list:

bioperl-l@bioperl.org

rather than to the module maintainer directly. Many experienced and reponsive experts will be able look at the problem and quickly address it. Please include a thorough description of the problem with code and data examples if at all possible.

APPENDIX

The rest of the documentation details each of the object methods. Internal methods are usually preceded with a _

    new



 Title   : new
 Usage   : my $obj = Bio::Symbol::Symbol->new();
 Function: Builds a new Bio::Symbol::Symbol object
 Returns : Bio::Symbol::Symbol
 Args    : -name    => descriptive name (string) [e.g. Met]
           -token   => Shorthand token (string)  [e.g. M]
           -symbols => Symbols that make up this symbol (array) [e.g. AUG]
           -matches => Alphabet in the event symbol is an ambiguity
                       code.



    name



 Title   : name
 Usage   : my $name = $symbol->name();
 Function: Get/Set Descriptive name for Symbol
 Returns : string
 Args    : (optional) string



    token



 Title   : token
 Usage   : my $token = $self->token();
 Function: Get/Set token for this symbol
 Example : Letter A,C,G,or T for a DNA alphabet Symbol
 Returns : string
 Args    : (optional) string



    symbols



 Title   : symbols
 Usage   : my @symbols = $self->symbols();
 Function: Get/Set Symbols this Symbol is composed from
 Example : Ambiguity symbols are made up > 1 base symbol
 Returns : Array of Bio::Symbol::SymbolI objects
 Args    : (optional) Array of Bio::Symbol::SymbolI objects



    matches



 Title   : matches
 Usage   : my $matchalphabet = $symbol->matches();
 Function: Get/Set (Sub) alphabet of symbols matched by this symbol
           including the symbol itself (i.e. if symbol is DNA
           ambiguity code W then the matches contains symbols for W
           and T)
 Returns : Bio::Symbol::AlphabetI
 Args    : (optional) Bio::Symbol::AlphabetI



    equals



 Title   : equals
 Usage   : if( $symbol->equals($symbol2) ) { }
 Function: Tests if a symbol is equal to another
 Returns : Boolean
 Args    : Bio::Symbol::SymbolI
